Learners should be taught to calculate with sums of money and convert between currencies; and understand that exchange rates of currencies are not fixed, but vary on a daily basis. Learners should also be taught to understand the difference between the selling and the buying rate of currency. Information Currency exchange rates are not fixed, they can vary from day to day. Current exchange rates are displayed in banks, daily papers and can be found on the Internet. There are two different rates. •
Selling Rate: The rate the bank sells you the foreign currency.
•
Buying Rate: The rate the bank buys from you the foreign currency.
The buying back rate is always higher because the bank will take a profit. Banks and Travel Agents generally take a commission. Examples Bank Selling Rate £1 = 1.32
Euro € U.S. dollar $

Bank Buying Rate £1 = 1.38

Learners should be taught to calculate, measure and record time in different formats; understand dates and times written in different formats; know how to use measuring instruments; know the relationship between units of time, e.g. sec, min, hr, day, week, month, year.
